Introduction

This module allows to create PostScript documents. It has many
similarities with the pdf extension. Actually the API is almost
identical and one can in many cases just replace the prefix of
each function from pdf_ to ps_. This also works for functions which
has no meaning in the PostScript document (like adding hyperlinks)
but will have an effect if the document is converted to PDF.

Documents created by this extension are sometimes even superior
to documents created with the pdf extension, because pslib's text
rendering functions can handle kerning, hyphenation and ligatures
which results in much better output of boxed text.
